8 Body Preparation
In order to install your ILM series liftgate, some body preparation may be required. Truck and trailer
applications with flush corner post and sill and NO protruding gussets or stiffeners are the most straight
forward of all ILM installations. Rear of body should be 90` to ground.
Note: Disconnect battery before welding to avoid damage to the truck or trailer‟s electrical system.
8.1 Rear Bumper
Steps:
1. Prep rear sill: Remove any sill or corner post mounted lights, grab handles, or bumpers, Fig.5. Your goal
is to have a flat and flush mounting surface for the liftgate.
It is not recommended to cut, torch, or remove support materials from rear sill of truck or trailer.
Installers are advised to sub-frame or flush sills as required. Removing gussets, stiffeners, light rings,
or other such support structures may VOID your truck body or trailer warranty.
2. Remove Rear Protrusions: Be certain that under ride bumpers, trailer hitches, or other auxiliary
equipment do not extend rearward of rear sill, Fig.6.
NOT Acceptable Acceptable

8.2 Tow Hitch/Auxiliary Equipment
Steps:
1. Relocate Hitch (If applicable): Trailer Hitches are common truck or trailer equipment and are compatible
with the ILM plus series, however they must not stick out further than the rear sill. Relocate or remove
tow hitch or other auxiliary equipment (If necessary) Fig.7.
If the tow hitch or other auxiliary equipment must be removed or adjusted, ensure that work is done by
a qualified professional. Removing or relocating tow hitches or other equipment may void the
warranty.

Revision 1.8 - 15 -
8.3 Flush the Sill (Sub- Framing)
Steps:
1. Flush the sill: Some trucks or trailers may have configurations with irregular shaped sills, Fig.8. Liftgate
mounting surface may NOT be flush with corner post. Some sills may be inset or have door gutters.
All these situations are remedied with a process called sub-framing and/or flushing the sill.
Sub-framing is done one of two ways; Sub-frame can be built up using correct size 3/16” or greater wall
tubing before liftgate is mounted. Or, the liftgate can be mounted into position and sub-frame can be built
as liftgate is installed with 3/16” or greater flat bar. In either case, liftgate installation weld procedure does
not change. These examples are show below.
Flushing floor or filling gap between Sill and liftgate can be done up to 6” without cross supports. Use ¼” or
greater flat bar or diamond plate to span gap. Original width of the truck frame should be matched as close
as possible.

2. Flat Bar Posts (if necessary): Corner stiffeners are common and should NOT be removed. It is
recommended to “flat bar” with same thickness as stiffeners, typically ¼” to 3/8” thick x 3” wide. Liftgate
Installation weld procedure is the same.

8.4 Support Body
Side supports can be used to strengthen body.
Steps:
1. Add body supports (If necessary): If extra support is required, add support bars.
Flatbed installation may use similar arrangement with 3/16” x 4” x 4”min. rectangular tubing for corner
post and 3” channels for support bar.

Revision 1.8 - 18 -
8.5 Add Alignment Bars (Optional)
The liftgate should be installed level to the rear sill. One method of doing this is to weld two alignment bars to
the rear sill. This acts as a “stop” as the liftgate is hoisted up. This step should be done before the liftgate is
raised to the vehicle. Other methods may also be used.
Steps:
1. Weld Alignment Bars: Weld two (2) supports to the sill of the truck. This will help ensure even alignment
between liftgate crossbeam and body sill. Use 3” angle or channel approximately 10” long.

9 Liftgate Preparation
The installer should never position any portion of him/herself, or any other person directly under the liftgate at any point during gate mounting.
9.1 Liftgate Preparation
The ILM liftgate comes with multiple assemblies and components attached that need to be removed prior to installation. Prepare the liftgate for installation by removing the following components and assemblies.
Steps:
1. Remove Parts Box: The box is tie wrapped to the traverse of the liftgate. Cut the tie wraps, open the box
and remove the power and hand held remote harness from the box, set the box aside.

10 Standard Liftgate Mounting
10.1 Hoisting the Liftgate
Before positioning the liftgate; consider when measuring and centering the liftgate that the truck or
trailer may NOT be square or parallel. Special care must be taken to ensure that the liftgate is square
and parallel before welding. Always disconnect the battery from the truck/trailer before welding to
avoid damage to the electrical system.
Steps:
1. Level Truck: Truck should be on level and even ground. Uneven ground will give misleading
measurements and can cause body twist or racking.

10.3 Column Modifications
When columns are too long and exceed the 18” maximum ground clearance they will need to be cut.
1. Measure Height: With the liftgate in its highest position, measure from level ground to bottom of the
column. Consider ride height at the vehicle‟s max load capacity, as well as dry unloaded ride height.
2. Mark Cut Line: Mark where the columns should be cut. Maximum ground clearance is 18”.
3. Cut Column: Cut the excess length of the column. Important: Always deburr after cutting by grinding the
inside and outside edges smooth. Chamfer the inside edge at 45°x1/8”, Fig.14. If the columns are not
deburred the slide pads will get damaged.

15 Lubrication
When kept properly lubricated, the PALFINGER ILM liftgate will ensure long lasting usage. Therefore, the
liftgate pivot points should be lubricated at the same time as the truck/trailer. Lubricate more frequently if the lift
gate is heavily used or whenever the pivot points appear to be dry. Average ILM plus use is considered 15
cycles per day or 1200 cycles per quarter.
DO NOT GREASE the “Slider Bearings” or “Columns” or “Runners”, as this will VOID your
WARRANTY on the slide bearings.
Column Lubrication: The columns are designed to run DRY and this is what Palfinger recommends first.
However, in some wet or dirty environments, the columns may require periotic lubrication. The schedule will
vary based on cycles, load, and environment. We recommend motor oil, 0W-20, 5W-30, or "bar & chain oil"
administered via a machinist style oil can. Don't over do it, a little goes a long way, two or three squirts on to
slide surfaces will last months in most cases, Fig. 27.
Deck: There are 2 grease fittings to maintain, left and right main pivots, Fig. 27.
Power Closing: There are 2 grease fittings to maintain, upper & lower cylinder pivot points.
Manual Closing Gates: Use a light penetrating oil on closing aids; left & right side, upper & lower gas spring
mounting points, Fig. 27.
Deck support chains: Use a light penetrating oil on chain anchors; left & right side, Fig. 27.
Lift roller chain: Under normal use and conditions, the lifting roller chain will require minimal lubrication or
maintenance as it is impregnated with good quality grease and only makes contact with Polymer sprockets. In
extreme wet or dirty environments, should roller chain show signs of drying or rust, lubricate with a good quality
motor oil or chain oil listed above for columns, Fig. 27.
ILM 16/20/25/30 Installation Manual
Revision 1.8 - 48 -
Lubrication Locations: All bearing points must be lubricated in accordance with the maintenance interval.

16 Cycle Test
16.1 Cycle Test and Bleed the Hydraulic System.
Improper use of the liftgate may result in serious injury. DO NOT operate this liftgate without being
properly instructed and fully understanding the Owner’s manual. Platform may crush or pinch. Make
certain area around liftgate is clear during all times of operation.
No bleeding of hydraulic system is required. System is a self-bleeding system and is pre-bled from the
factory. Test steps a minimum of five (5) times each to ensure NO unusual noises or movements are
found. This will confirm all controls work correctly and hydraulic system is completely bled of air.
